Really fantastic quality from a reputable supplier.
Fantastic clarity, really clear to get maximum light transmittance and what would just top this and make this the best on Amazon would be a little kit to go with it or bought separately where you would make a frame like a picture frame only with no backing. I actually purchased this for a science experiment with my nephew where we could measure its temperature at its optimum focal length and it's brightness. I mean this thing put a magnifying glass to shame. We had the temperature up to 1980 C. Hot enough to melt brass. We actually melted a brass pad lock off my nephews bike as he had lossed the key to it. WORD OF WARNING: WERE EYE PROTECTION LIKE WELDING HELMET AS THE BRIGHTNESS IS SUPER INTENSE !!!

muy bien
llego rapido y sin ningun daño en la lente, me imagine que vendria con el marco para sujetar la lente como en la foto pero no es asi, viene solo la lente.

Große Fresnellinse (39,5 x 39,5 cm) mit guten optischen Eigenschaften
Die Fresnellinse besteht aus einem spröden Kunststoff, der bei der ersten Lieferung leider zerbrochen bei mir ankam. Der Händler aus GB hat aber sofort und superfreundlich für eine Ersatzlieferung gesorgt. Ich habe die Fresnellinse nun in einen Bilderrahmen eingebaut um zukünftig ein versehentliches Durchbrechen zu verhindern. Bin sehr zufrieden mit der optischen Qualität.

Super Lentille
j'ai acheté cet article pour faire démarrer un petit feu de barbecue, et pour quelques branches mortes dans mon jardin ça marche super bien (veillez quand même au règlementations préfectorales pour les périodes d'autorisations à faire du feu dans votre jardin), il suffit de concentrer un point de lumière sur du papier ou du bois et en plein soleil , sans nuages, une flamme apparait instantanément. donc attention ça brule. état neuf de très bonne qualité,.. j'en suis super content. livraison rapide.

Parfait!
Cette lentille de Fresnel correspond à ce que j'attendais. Délai et livraison ok! A voir sur la durée la qualité du matériau utilisé.
